The minimum requirement of proposed antenna is having 400 GHz impedance bandwidth under -10 dB with working frequencies at 8.0 GHz-8.4 GHz. The proposed antenna will be developed in circularly polarized mode. Thus, the axial ratio must be under 3dB at the desired frequencies. To ensure the antenna design fulfilling all the minimum requirements, some techniques are implemented, for example, triangular truncation factor, ring slot with ellipse shape in the middle of patch, and sequential rotation with relative phases 0 degrees, 90 degrees, 180 degrees, 270 degrees. Then the radiator of antenna is formed by a circular shape. The proposed antenna could fulfil satisfied results. The impedance bandwidth of antenna is obtained 1.8 GHz (7.5 GHz-9.3 GHz). The simulated gain reached 12.5 dBic at the center frequency and the axial ratio bandwidth is 1.17 GHz (7.3 GHz-8.47 GHz). The antenna design is printed at an NPC H220A dielectric substrate with the dielectric constant of 2.17, the thickness of 1.6 mm, and the sizes of 60.92 mm x 60.92 mm.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Axial ratio bandwidth,Broadband,Dielectric substrates,Impedance bandwidths,Left handed,Minimum requirements,Sequential rotations,Space-borne[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Broadband,Left Handed Circular Polarization (LHCP),Microstrip antenna,Space borne,Synthetic Aperture Radar (SAR)[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors would like to thank Chiba University Strategic Priority Research Promotion Program FY2016-FY2018, Chiba University Institute of Global Prominent Research FY2016-FY2018, RISET-Pro Program of Ministry of Research, Technology, and Higher Education, the Republic of Indonesia, and National Institute of Aeronautics and Space of Indonesia (LAPAN).[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/CAMA47423.2019.8959576[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
